30W RF Laser Tube For Engraving, Higher precision Smaller laser spot size, it can engrave ultra-fine details .Longer life ,it can be used for about 10-12 years.The engraving effect is non-scorched and non-black. Higher power CO2 Laser Tube for cutting, More cost-effective Optional 40-100W CO2 laser tube, capable of cutting thicker materials,cheaper than the RF tube.Using Yongli laser tube, its photoelectric conversion efficiency is high, the laser output power density is high, the beam is concentrated, and the spot is uniform. The engraving/cutting speed is fast and the engraving line is deep and narrow with high resolution and clear characters. The work life of laser tube is long and the fault rate is low.
